IMPROVEMENT IN DUMPlNG-CARS.

The Schedule referred to in these Letters Patent and makingpafi: of theme.

To all whomit may concern:

Be it known that I, PETER. K. DEDERIGK, of Albany, in the county of Albany and State of New York,

have invented a new and useful Improvement in Goal- Oars; and I do hereby'declare that the following is a full and exact description thereof, reference being had to the accompanying drawing and to the letters of reference marked thereon.

My invention belongs to the class of cars used for moving, by hand, on either elevated or ground tracks; and consists in constructing the car with the bottom sloping both ways overthe wheel, so that the coal will slide when the doors are opened. Also, in opening and closing the discharging-door by means of a crank or cranks.

, In the accompanying drawing- Figure 1 is a bottom view of my car.

Figure 2 is'a transverse'sectioh of the same.

My improvement may be employed on any suitable truck, A, figs. 1 and 2.

The body, B,of the car is provided with discharging-doors O, which are operated bya crank or cranks, D, in connection with'ha-nd-lever E and connectingrods F, thus releasing the doors for discharging, or looking them shut, when the cranks are turned on the center.

The bottom of the bar slopes toward the sides, as shown in the V-shaped section seen at G, fig. 2. The

wheels are located under the sloping bottom, thus bringing the body very low, and discharging the coal or dirt entirely over and outside the track and wheels.

The cranks or crank D may he used for operating the discharging-doors of the bottom dump-cars as well as side dump, and with the same advantages, and chains maybe substituted for the rods connecting the cranks to the doors, if desired, withthe same effect.

The cranks for opening the doors are located underneath the V-shaped bottom, and are formed on the shaft by forging it to shape, as shown in the drawing, thus allowing both of the cranks to move entirely on or a little past the dead-center, or so that the pressure against the door-s will fall direct] y against the shaft, thus obviating the necessity of retaining rat-chets or other fastenings, which are indispensabie when the cranks are prevented from moving over the dead-centor by the connecting-rods striking the shaft to which they are attached, or by interfering with each other.

Having thus described my invention,

Iclahn- Y The car with a V-shaped bottom, in combinatior with a double crank-shaft located underneath, when connected and operated substantially as described.
